　　Section B

　　Talk One

　　M: I’m looking for Mrs. O’Reilly’s office.

　　W: I’m Mrs. O’Reilly. Come right in.

　　M: I was at the Student Health Services yesterday. They told me that my blood pressure is too high.

　　W: Then I suppose you need a low-sodium diet to help bring your blood pressure down.

　　M: That’s right. The doctor told me to see the university nutritionist about it, so here I am. He gave me this note for you.

　　W: Let’s see. It says here that you can have up to three grams of sodium a day. One moment. Ah, here’s the one. This is a chart of the sodium content of different foods.

　　M: Oh, no. Good-bye to potato chips and snack-bar hamburgers!

　　W: Yes, and good-bye to processed foods in general. But you can have almost all fruits and vegetables with a few exceptions like spinach.

　　M: That part’s OK. I hate spinach. What worries me is—where do I eat? Do I have to eat at the university hospital while my friends eat in the dining-hall?

　　W: Not at all. I’ll just call the dining-hall manager. He handles all sorts of special menus—low calorie, low cholesterol, diabetic… He’ll see that you don’t go over your three grams.

　　M: What if I want to go to a restaurant?

　　W: Just use your chart and select your food carefully.

　　M: Thanks a lot. This won’t be nearly as bad as I thought it would be.

　　Talk Two

　　Word comes from California of a new weapon in the war on household pests. Two scientists working for a firm in Anaheim, California, have developed a method to eliminate insects without using dangerous chemicals. The new poison? Hot air.

　　The basic idea is that insects cannot adjust to temperatures much above normal. In laboratory experiments, cockroaches and termites can’t survive much more than a quarter of an hour at 125 degrees Fahrenheit, or about 50 degrees Centigrade.

　　The new method involves covering a house with a huge tent and filling it with air heated to around 65 degrees Centigrade. Hot air is forced in with fans, and the tent keeps the heat inside the house. Since termites try to escape by hiding in wooden beams, the heat treatment must be continued for a full six hours, but when it’s all over, the insects are dead, there are no toxic residues to endanger humans or pets, and no funny smells. Scientists claim that there is no danger of fire, either, since very few household materials will burn at 65 degrees Centigrade. In fact, wood is prepared for construction use by drying it in ovens at 80 degrees Centigrade, which is substantially hotter than the air used in this procedure.

　　21. What is the talk mainly about? B)

　　22. According to the speaker, what makes the new system better than other treatments? B)

　　23. Why are the houses covered with tents? A)

　　Talk Three

　　I’m sure you realize that your research papers are due in six weeks. I’ve looked at your proposed topics and made comments about them. The most frequent problem was proposing too broad a topic. Remember, this is only a fifteen-page paper.

　　As I return your topic papers, I’d like to look over the schedule which sketches out what we’ll do during the next two weeks. Today is Monday. By Friday, I want your preliminary outline. Please be sure to incorporate the suggestions I’ve made on your topics in your outlines. Next week I’ll have a conference with each of you. I’ve posted a schedule on my office door. Sign your name to indicate the time you’re available for an appointment. In the conference, we’ll discuss your preliminary outline, which is due two weeks from today. Use the outline style in your textbook and remember it should be no more than two pages long. Be sure to begin with a thesis statement, that is, with a precise statement of the point you intend to prove, and include a conclusion.

　　Have you got all that? Your two-page preliminary outlines are due at the end of this week and the final outlines are due after your conferences. Follow the textbook style and include a thesis statement and a conclusion.

　　26. What did the speaker probably do before this class? A)

　　28. When will conferences be held? B)

　　29. What is the purpose of the conference? C)
